Tamil Nadu Public Service Commission [TNPSC] — Group 2 exam application

I am an architect graduate .I have requested to update my aadhar details and it's in process. Tnpsc updated the rule of linking the aadhar with OTR before 30/4/2022 . Whereas candidates can apply for group 2 exam now and link aadhar with OTR before April 30. But I am not able to apply for group 2 exam without aadhar. There is no option to apply after I login to OTR. I enquired help desk through call, email and in-person visit .They dint help me . They were talking as the updated Tnpsc rule is fake. And aadhar link with OTR is mandatory .I got to miss the exam . Highly disappointed.
